Try to do this. Go to Mozilla.org or
Firefox In Any Language
and get the full installer. After you get it, uninstall the current FF. After a
reboot, then run the new installer program. Let us know how you did.

I once had problems with a Windows update. While the install program
downloaded, it could not replace the old program with the new. After a
LOT of on line and help searching, I discovered that the uninstall file for
the old program was missing. Going back to Microsoft help, I found the
FIX-IT programs. Once I told FIX-IT what program was giving me problems,
that was it. After, I finished the updates. Go to this web page and check
it out;Fix problems that programs cannot be installed or uninstalled

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

(32 bit Windows) "C:\Program Files\Mozilla Firefox\"

(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps to remove the program.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
